RFM700 series refractometers are robust, low cost, fully automatic instruments that are ideally suited to the food, sugar and beverage industries but can also be used in many other non food applications where use of a waterbath for temperature control is not required.

The RFM700 series features robust construction, a sapphire prism mounted in an easy clean st. steel dish and an outer casing that is sealed and shaped to withstand sample spillage and moisture ingress. This together with the external power supply makes the RFM700 ideal for use in a harsh factory environment or busy laboratory. The red LED display is clear and visible in dim or bright lighting and includes scale and temperature compensation indicators. Four graphically represented multiple function keys provide simple user interfacing without the requirement to interpret legend.

Commonly, the RFM700 series refractometers are supplied to operate in the °Brix scale with results temperature compensated to 20 °C in accordance with ICUMSA. Additional user scales provide measurement in different formats such as various wine, Refractive Index (RI) and FSII as well as allowing custom scales to be loaded in accordance with product data. Product specific temperature compensation may also be input to the RFM700 series refractometers providing a corrected reading whatever the instrument temperature.

The RFM700 series facilitates span calibration at any value using a variety of media types, as temperature compensation may be adjusted to suit the product being used. Additionally, the instruments are fitted with AG temperature compensation, allowing the use of AG Fluids without the need to use conversion table.

Sample temperature stability is also important. The RFM700 series allows the input of a delay time that forces the operator to wait for countdown before reading, ensuring reliable results every time. The instrument can also be connected to a printer or laboratory PC, with results being output in printed or CSV formats.
